  • Allergen Specific Immunotherapy

    Allergen immunotherapy (AIT) has been used to treat allergic disease since the early 1900s. Despite numerous clinical trials and meta-analyses proving AIT efficacious, it remains underused and is estimated to be used in less than 10% of patients with allergic rhinitis or asthma worldwide. In addition, there are large differences between regions, which are not only due to socioeconomic status. There is practically no controversy about the use of AIT in the treatment of allergic rhinitis and allergic asthma, but for atopic dermatitis or food allergy, the indications for AIT are not well defined. The elaboration of a wider consensus is of utmost importance because AIT is the only treatment that can change the course of allergic disease by preventing the development of asthma and new allergen sensitizations and by inducing allergen-specific immune tolerance.

    Chronic rhinosinusitis (CRS) is a public health problem that has a significant socio-economic impact. The complexity of this disease due to its heterogeneous nature based on the underlying pathophysiology - leading to different disease variants - further complicates our understanding and directions for the most appropriate targeted treatment strategies. Several International/national guidelines/position papers and/or consensus documents are available that present the current knowledge and treatment strategies for CRS. Yet there are many challenges to the management of CRS especially in the case of the more severe and refractory forms of disease. Therefore, the International Collaboration in Asthma, Allergy and Immunology (iCAALL), a collaboration between EAACI, AAAAI, ACAAI, and WAO, has decided to propose an International Consensus (ICON) on Chronic Rhinosinusitis. The purpose of this ICON on CRS is to highlight the key common messages from the existing guidelines, the differences in recommendations as well as the gaps in our current knowledge of CRS, thus providing a concise reference.

    The ICON: Anaphylaxis paper focuses on the principal anaphylaxis guidelines developed and published independently by the collaborating organisations from 2010 to 2014, other anaphylaxis-relevant guidelines and publications from these organisations, and more than 100 additional key publications that contribute to the evidence base for diagnosis, management, and prevention of anaphylaxis recurrences. In addition, it describes unmet needs in the diagnosis and treatment of anaphylaxis in high-, mid-, and low-resources countries and proposes an international agenda for anaphylaxis research.

    Drug hypersensitivity reactions (DHRs) comprise all drug reactions resembling allergy. DHRs constitute 15% of all adverse drug reactions affecting more than 7% of the general population. DHRs can be allergic or non-allergic with immunologically-mediated DHRs being named drug allergies. They are typically unpredictable, necessitate treatment changes and can potentially be life-threatening. A definitive diagnosis enabling the institution of adequate treatment options and proper preventive measures typically requires a complete drug allergy work up. Several guidelines and consensus statements on general or specific drug class-induced DHRs are available to support medical decisions on drug allergy; however, a standardized systematic approach for the diagnosis and management of DHRs is still a major challenge. The International Collaboration in Asthma, Allergy and Immunology (iCAALL), formed in 2012 by EAACI, AAAAI, ACAAI, and WAO, addresses this unmet need in this International Consensus on (ICON) Drug Allergy document. The purpose of this document is to:
    • highlight the key messages that are common to many existing guidelines
    • critically review and comment on differences, thus providing a concise reference

    Primary immunodeficiencies are intrinsic defects in the immune system that result in a predisposition to infection and are frequently accompanied by a propensity to autoimmunity and/or immunedysregulation. Primary immunodeficiencies can be divided into innate immunodeficiencies, phagocytic deficiencies, complement deficiencies, disorders of T cells and B cells (combined immunodeficiencies), antibody deficiencies and immunodeficiencies associated with syndromes. Diseases of immune dysregulation and autoinflammatory disorder are many times also included although the immunodeficiency in these disorders are often secondary to the autoimmunity or immune dysregulation and/or secondary immunosuppression used to control these disorders. Congenital primary immunodeficiencies typically manifest early in life although delayed onset are increasingly recognized. The early diagnosis of congenital immunodeficiencies is essential for optimal management and improved outcomes. In this International Consensus (ICON) document, we provide the salient features of the most common congenital immunodeficiencies.

    The first ICON was the ICON on Food Allergy and was launched in March 2012 during the Anual Meeting of the American Academy of Allergy and Clinical Immunology (AAAAI) in Orlando.

    This ICON is published in the Journal of Allergy and Clinical Immunology (JACI).

    The second ICON report was launched during the EAACI Congress 2012 in Geneva. The goal of the International Consensus (ICON) on Pediatric Asthma is to highlight the key messages that are common to many of the existing guidelines, while critically reviewing and commenting on their differences, thus providing a concise reference. The Pediatric Asthma ICON provides advice for the best clinical practice in pediatric asthma management.

    The Pediatric Asthma ICON is published in Allergy, the European Journal of Allergy and Clinical Immunology. Click here to read this ICON in Allergy.

    Prof. Nikos Papadopoulus, EAACI  Secretary General and Pediatric Asthma ICON Chair said: “Despite available treatments, less than 50% of asthmatic children control their symptoms”. “Pediatric asthma is a chronic disease and therefore, requires chronic treatment. With this Consensus we highlight that pediatric asthma can be controlled by establishing a partnership between patient and doctor and adhering to a well-designed personal management plan. Regular monitoring ascertains the effectiveness and fine-tunes treatment”, he explained.

    The ICON on Hereditary and Acquired Angioedema was released 9 November 2012 during the Annual Scientific Meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Anaheim, California.

    “There is an international lack of understanding, consensus-driven information and general recommendations for angioedema,” said David M. Lang, MD, chair of the ICON Hereditary and Acquired Angioedema and ACAAI Fellow. “This ICON report will help ensure the proper diagnosis and management of all forms of angioedema, while helping patients find relief and live healthy, active lifestyles.”

    This ICON is published on Annals of Allergy, Asthma and Immunology.

    The ICON on Eosinophil Disorders was released on December the 7th, 2012, during the 2nd WAO International Scientific Conference (WISC 2012) of the World Allergy Organization in Hyderabad, India.

    “Although scientific achievements in the field of eosinophilic disorders have led to improved diagnosis and therapy for patients, a global consensus has been needed,” said Lanny J. Rosenwasser, M.D., chair of the ICON on Eosinophil Disorders. “The ICON provides a diagnostic algorithm, along with redefined criteria, terminologies and classifications of eosinophilic disorders, based on the latest developments published in the field and the work of individuals and groups focused on explaining the complexities of eosinophilic disorders. The report will aid physicians in providing treatment for patients that is targeted to the specific type of eosinophilic disorder. It also identifies several unmet needs in this disease area that need to continue to be addressed in a multi-disciplinary way.”

    The full report is published in the December 2012 issue of the World Allergy Organization Journal.
